10. A method for operating a battery pack comprising a battery module, the method comprising:
-
sensing whether or not the battery module is swollen; monitoring a state of charge of the battery module; determining whether a state of the battery module is a charging state or a discharging state; when the state of the battery module is the charging state, determining whether or not the state of charge is greater than or equal to a charging limit; when the state of the battery module is the discharging state, determining whether or not the state of charge is less than or equal to a discharging limit; and controlling the charging and discharging of the battery module according to at least one of the state of the battery module, the state of charge of the battery module, or whether or not the battery module is swollen. - View Dependent Claims (11, 12, 13, 14, 15)
